Operational Overview
The Digital Solutions BVE02 interface enables a Yamaha DM1000, 02R96 or DM2000 digital
recording console to be controlled by a Video Edit Controller or Vision Switcher using the
ESAM command protocol.
When connected to a Video Edit Controller, the mixing and monitoring of forty channels of
source audio may be controlled directly from the edit controller, with all edits and crossfades
stored and recalled as part of the edit decision list (EDL) held on the Edit Controller.
When connected to a Vision Switcher, the BVE02 automatically mixes the audio channels for
sources selected to the Program bus on the Vision Switcher.
In both scenarios, the audio mixer may be used with two or four audio-channel VTRs, servers,
cameras or Outside Sources and will mix signals to a two, four or eight channel mix bus.
The versatile system display and the motorised channel faders of the mixer enable the status
of the mixing, controlled by the edit controller or visions switcher to be easily observed.
BVE02-PV
The BVE02-PV adds the ability for sources opened to a Vision Switcher’s Preset bus to be
auditioned on the audio mixer and the fader levels for that source adjusted before the source
is opened to the Program bus. Uniquely, when the BVE02-PV is connected to a Snell Kahuna
Vision Switcher, it also allows multiple sources to be opened simultaneously to the program
bus of the audio mixer.
The BVE02-PV is ideally suited to single-operator galleries, such as those used for local news
or magazine programming, where one person is responsible for both vision and audio mixing.
BVE02-AFV
The BVE02-AFV allows the creation of a complete audio mix, using all the faders of the mixer,
for each vision source. The BVE02-AFV includes an external control panel that gives quick and
simple control of the system for creating and updating each mix, whether during offline
preparation or while on-air.
The BVE02-AFV is most effectively employed in the production of fast-moving sports
programming such as motor sport, skiing, air shows or air racing.
Basic Operation
When executing edit transitions, crossfades or cuts under the control of the Edit Controller or
production Vision Switcher, the mixer operates in a very similar manner to a video switcher. In
order to simplify the selection and control of the mixer channels, the group of inputs which
carry the audio signals from an individual VTR, server channel or other video source are
considered as a single entity and are referred to as a Machine. The channels which make up a
Machine are listed in the ‘Machine Assignments’ section of this manual.
The Edit Controller will have a configuration page which holds information on each VTR it is to
control, including the Machine control port number, the video switcher input number, and the
audio mixer Machine number for each source. The Vision Switcher in a production gallery or
OB truck will have a similar configuration page identifying each connected source and either
